For good health, everyone knows that you need to drink eight cups of boiled water every day, and the electric kettle is one of the essential appliances in almost every household . When you want to drink water, you can boil a pot with an electric kettle. It can be said to be very convenient.

It is rumored that stainless steel electric kettles contain manganese , which will be released during the boiling process. Drinking this water for a long time will lead to excessive manganese , which will damage human nerves and even cause cancer . Is this really true?

Xiong Jinping, a professor at the School of Materials Science and Engineering at Beijing University of Chemical Technology, pointed out: Although the stainless steel electric kettle contains manganese, it is difficult to dissolve during the process of boiling water . Even if it is continuously boiled repeatedly for more than 1,000 hours , the precipitated manganese is in ionic form , has little impact on the human body, and has no risk of cancer .

For safety reasons, electric kettles must be purchased as regular products that meet national standards .

Professor Xiong Jinping reminded: Electric kettles on the market can be divided into glass, stainless steel, and ceramics . different materials such as

When purchasing a stainless steel electric kettle, try to choose one with the words “for food contact” or “implementation standard GB9684-2011” ;

Many people believe that the increasing number of kidney diseases in our country is caused by tap water. There are also claims that hard water can cause kidney stones…

Yun Wuxin, a Ph.D. in food engineering from the Department of Agricultural and Biological Engineering at Purdue University in the United States, pointed out: The hardness of water is mainly related to the concentration of calcium and magnesium in it . The national standard for tap water in China is that the total hardness does not exceed 450 mg . Even if you drink two liters of hardness per day, Water will not exceed the calcium limit.

after boiling Moreover, some calcium and magnesium ions will turn into scale , so there is no need to worry about getting kidney stones from drinking water normally . Whether it is soft water, hard water or pure water, as long as other indicators are qualified, it will not have a big impact on health. .
